DEVICE FOR OPENING AND CLOSING WINDOW-SASHES.

Specification of Letters Patent.

Patented Jan. 14, 1908.

Application filed April 6. 1907. Serial No. 366334.

To all whom it may concern:

Be it known that I, ADoLPH PLAss, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in a Device for Opening and Closing VVindow-Sash and Similar Structures, of which the following is a specification.

My invention relates to improvements in a device for opening and closing window sash, shutters or other similar structures, and the object of my invention is to provide a simple and effective means whereby a row or series of window sash or shutters may be simultaneously operated from a central or common point, my device being adapted to the style of window sash or shutter which swings on a pivot, is hinged, or which slides in a casing, either horizontally or perpendicularly.

My invention is illustrated in the accompanying drawings in which Figure 1 is a view of the device applied to a swinging sash pivoted near the center; Fig. 2 is a sectional view of the same on the line as w of Fig. 1 Fig. 3 is a view in cross-section of the collar detached Fig. 4 is a view of the antifriction roller and pulleys; Fig. 5 is a view of the rod operating mechanism.

Similar letters refer to similar throughout the several views.

A channel iron a is secured to the fixed structure I) on a line with the horizontal plane of the pivots upon which the window sash c and (Z swing. On this channel iron a I secure the pulleys c and f at one side of the window 0, by means of hinged sleeves e and respectively, thus permitting the pulleys to swing with the sash as it is opened or parts closed.

Upon the channel iron a at suitable intervals, is secured roller bearings m provided with an antifriction roller n. A rod 11 extends along the line of the window sash at the plane of the pivots, passing through the roller bearings m and resting upon roller n. Collars 0 and p are secured to the rod L by set screws 0 and 19 respectively. A cable or chain k is secured to the window sash 0 above the line of the pivots by a screw or other suitable means, and passes downwardly around the pulley f to the collar 0, where it is secured by a set screw 0 or other suitable means.

A cable or chain Zis secured to the window 1 sash 0 below the line of the rod t, and passes upwardly around the pulley e to the collar 1), where it is secured by a set screw or other suitable means. In like manner a cable or chain 9 is secured to the upper side of the sash (1 above the line of the rod i, and passes around the pulley h to the collar 0, where it is secured by a set screw or other suitable means. The pulley h is set back from the plane of the pulley f so that it will not interfere with the chain 76. A cable or chain (1 is secured to the sash d above the line of the rod i, by suitable means, and passes downwardly around the pulley h to the collar 0 where it is secured by a set screw or other suitable means. A cable or chain 1" is secured to the lower side of the sash d by a screw or other suitable means, and passes upwardly around the pulley g to the collar p where it is secured by a set screw p or other suitable means.

I have shown in my drawings only two sash of the series, but the device maybe applied in like manner to as many window sash as is desired.

Similar pulleys and chains are used at each window sash, the chains at the other sash of the series being secured by the collars upon the rod i in a similar manner.

My device being assembled as above described, the upper portion of the window sash may be drawn inwardly toward the plane of the pulleys, by moving the rod & to the right, as the collar 0, being fixed upon the rod will move with the rod and draw the chains 9 and 76 around the pulleys hand f respectively, and the tension upon the chains thus created will draw the upper ortions of the sash d and c inwardly, in the irection of the vertical plane of the pulleys. When it is desired to draw the lower portion of the sash inwardly, the rod 4. is forced to the left, thus which the chains 1' and Z are secured, thus drawing the lower portions of the sash inyvardly toward the vertical plane of the puleys. Y

I prefer to move the rod "L by means of a wheel, internally screw threaded, to fit into screw threads upon the end of the bar, as shown, but the rod i may be moved by a lever by rack and pinion, or other suitable means. While I have shown cables and pulleys in my drawings, 1 do not mean to limit myself to this particular form of construction, as any drawing the lower chains 1 and Z around the pulleys g and e, by means of the collar 10, to

well known equivalent may be used, such as a cable, or rods and bell crank. I have further shown my device applied to asash swinging upon a central pivot, but it may be used without change for a sliding or hinged sash, the tension upon the chains drawing the sash in the desired direction.

Having thus described my invention, what I claim is 1. In a device of the character described the combination of a window sash, a rod movable along the line of the window sash, a collar secured to the rod, a roller bearing supporting the rod, a connecting means between the window sash above and below the plane of the rod, and pulleys intermediate of the ends of the connecting medium, substantially as shown and described.

.2. In a device of the character described, the combination of a window frame, a bearing secured thereto, a roller within the bearing,,a rod movable horizontally upon the bearing, a collar secured to the rod, and a series of connecting means secured to the window sash above the horizontal plane of the rod, and a series of connecting means secured to the window sash below the horizontal plane of the rod, and pulleys intermediate the ends of the connecting means, substantially as shown and described.

3. In a device of the character described, the combination of a window frame, a bear- 'ing secured thereto, a roller within the bearing, a rod upon the bearing movable hori- Zontally, a collar secured to the rod, a series of connecting means secured to the window sash above the horizontal plane of the rod, and a series of connecting means secured to the window sash below the horizontal plane of the rod, substantially as shown and described.

4. In a device of the character described, the combination of a rod, a series of window sash each pivoted at its center, and in the plane of the rod, supporting means betw'eenthe rod and the fixed structure sustaining the window, whereby the rod is held'beyond the vertical plane of the window, connecting means between the free end ortion of the Window and the rod, and a pul ey intermediate of the ends of the connecting means, other connecting means between the other free end ortion of the window and the rod, and a pulley intermediate of the ends of said connecting medium, whereby a movement of the rod in one direction will draw the one free end portion of the window toward the plane of the rod, and a movement of the rod in the opposite direction will draw the other free end portion of the window toward the plane of the rod substantially as shown and described.

5. In a device of the character described, the combination of a rod, a series of window sash, each pivoted at its center and in the plane of the rod, a series of collars, each secured to the rod at a point between the sides of the window sash, supporting means between the rod and the fixed structure supporting the .window, whereby the rod is held beyond the vertical plane of the window, connecting means between the free end portion of the window and the collar secured to the rod, and other connecting means between the other free end portion of the window and the other collar upon the rod, whereby a movement of the rod in one direction will draw the one free end portion of the window toward the plane of the rod, and a movement of the rod in the opposite direction will draw the other free end portion of the window toward the plane of the rod, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
